BaliPeter: There are more then 250 comments posted on this light leak issue, so obviously there is a problem. All my lenses and camera's are Canon and I just bought the Mark III. What I find rediculous about it all is the way a reputable manufacturer like Canon handles an engineering fault. If Canon where a car manufacturer they would recall all related models and fix the problem. I didn't pay $3000 + for a piece of equipment to have to put duct tape on the inside of an LCD screen, as suggested by some. Canon is responsible for their mistakes and should fix it, simple.

Stanley Zheng, No body asked me to put duct tape, someone wrote that he put some duct tape on the inside of his LCD screen, which I don't want to do when I buy an expensive piece of equipment. To me it doesn't matter if the fault is small or big, a fault is a fault and Canon should fix it. 1/3, 1/2 or 3 steps or stops, which ever you prefer, is just not acceptable in my view. To your question what there is to be fixed? It is what Canon themselves call a "Light Leak", that is all, sounds like contradiction to me, photography and leaking light. Cheers and have fun anyway.
